Specification of Letters Patent.

Patented July 18, 1911.

Application filed August 24, 1910. Serial No. 578,787.

To all whom it may concern:

Be it known that I, \VILLARD D. BAKER,

a citizen of the United States, residing at Rogers, in the county ofBenton and Stateof Arkansas, have invented a new and useful Fly-Trap forScreen-Doors, of which the following is a specification.

The invention relates to a screen doors. a

The object of the present invention is to improve the construction offly traps and to provide a simple, inexpensive and eflicient fly tradesigned to be mounted ona screen door or catching the flies, whichaccumulate on the latter, and capable of being readily removed fordestroying thecaptured insects and readily replaced when the same havebeen em tied from the trap.

A further 0 ject of the invention is to pro vide a fly trap to hold abait 1n position for attractin the flies to the entrance of the trap and0 retainingethe same in place to prevent the bait from ing dislodgedbythe openingand of a screen door.

Wit these and other objects in view, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawing, and ointed out in the claimshereto appende it being understood that various chan es in the form,proportion, size and minor etails of construction, within the scope ofthe claims, may be resorted to without departing from the spirit orsacrificing any'of the advantages of the inventitin.

In the drawir{i g:Figure 1 is a erspective view of a y-trap, const-ructein accordance with this invention and shown ap plied to theupper portionof a screen door. Fig. 2 is a transverse sectional view of the same.Fig. 3 is a horizontal sectional view.

Like numerals of reference designate corresponding parts in all thefigures of the drawing. "y

In the embodiment of the invention illusfly trap for trated in theaccomganyingdrawing, the fly trap 1 is mounte upon the top bar or rail 2of a screen door 3, and it comprises in its construction asheet metalwall or back 4, and a top, front bottom and end walls of woven wire, orother screen material. The sheet metal wall 4 has extended terminals 5,and is provided intermediate of its ends witha longitudinal slot oropening 6, which &

of this character, adapted is normally covered by a slidable closure 7,mounted in guidm or ways 8, formed by bendin the upper and lower edgesof the rear wa l or back 4 to form inwardly extending approximatelyL-sha ed flanges. The trap is secured to the oor by means of screws 9spaced from the trap and having thumb nuts 10, which admit of the readyremoval of the trap for destroying the captured insects. The screws 9'are mounted on and roject horizontally from the to rail of the door, andthey extend through vertical slots 11 of the extended terminals 5 andthe end portions of the slide or closure 7, which is retained in placeby the fastening devices that secure the trap to the screen door. Whenthe trap is detached from the screen door, the slidable closure may bereadily withdrawn from the guides or ways for emptyin the insects afterthe latter have been kil ed by hot water, or other suitable means.

The rece tacle or trap 1 is preferably rounded at t e upper frontportion, as shown, and it is supported at the end walls by marginalframes 12 of wire, or other su'itable material, and its bottom iscomposed of upwardly extending op ositely inclined sides or members 13,spaced apart at their upper edges to provide an entrance to the trap andforming a bait-receiving space between them. The wire end frames 12extend around the ends of the trap and have in- .clined terminalportions 14, conforming to ofjthe drawing. The side frames are alsoprovided with horizontal connecting portions 15, arranged at the bottomof the baitreceiving space 16 and forming supports for a bait-holdingtrough or receptacle 17. The bait-holding trough or receptacle 17consists of a horizontal bottom, a vertical end wall, and inclined sidewalls 18, converging upwardly and adapted to confine a strip 19 of feltor other suitable material upon which the bait for attracting theinsects is smeared. The bait strip 19 is folded, as shown, in Fig. 2,and it extends under the inclined side-walls of the trough and itis-retained in place by the same and is prevented from being dislodgedby the o ening and closing of the screen door. The files allghting onthe screen crawl u )ward until they reach the trap or the vicinitythereof, and they are then attracted by the bait and after feedirwthereon continue screen door and is adapted to catch the flies andprevent them from entering a house when the screen door is .open.

The effectiveness of the screen is increased by arranging the bottom atan inclination and dro pin the outer portion of the trap or receptac ebe ow the level of the inner ortion so as to form an over-hanging hoo asclearly shown at 1" in Fig. 2 of the drawing. The screen door isprovided at its upper portion with a slot or outlet 21, located beneaththe trap and adapted to permit flies from the interior to .pass outwardand enter the tra The bait-holding trough is soldered, or ot erwisesecured to the horizontal sup orting portions 15 of the end frames, andthe bait-receivin s ace between the inclined side portions 0 't e bottomis 0 en at the end Walls 22, which are provided at their lower portionswith triangular openings 23 of greater size than the bait trough'andstrip,but terminating short of the entrance opening 20 and havingrojecting edges 24 at the openings 23. he projecting edges formextensions or marginal flanges at the ends of the bait-receiving openingto prevent the flies crawling u ward on the inclined side portions of te bottom from passing directly out of the openings at the ends of thebait-receiving s ace. The projectin flange 24 will turn t e flies backand w' cause them to continue their upward crawling. One end 25 of thebait-holding trough-is open to enable the bait strip to be readilyplaced in and removed from the trough. Both ends of course may be open,if desired. While the flly trap is designed primarily for and is s ownapplied to screen doors, yet it may be m y closures.

Havin thus fully described my invention, what I aim as new and desire tosecure by Letters Pat is 1. A device of the class described comprisinga. trap rovidedat the bottom with an entrance an having a rear wallpi-ovided with an opening communicating with the interior of the trap,said rear wallbeing also on screens for windows or other provided withterminal attaching portions extending beyond the tra a closure coveringthe said opening an having terminal attaching portions extending beyondthe trap and arranged in rear of the terminal attaching portions of therear wall, and fastening devices spaced from the trap and passingthrough the extended portions of the rear wall and the closure forsecuring the trap to a suitable support and for retaining the closure inlace.

2. A device of the c ass described including a trap provided at thebottom with an entrance and havin 1 a rear wall provided with extendedtermlnal attaching portions,

said rear wall being also provided with opposite grooves or ways andhaving a slot or opening communicatin with the interior 0 the trap, anda slida le closure mounted in the grooves or ways and having itsterminals arranged at the terminal attaching ortions of the rear wall soas to be retained 1n place by the fastening means for securing the trapto a screen door or other support.

3. A device of the class described com risinga traphaving a bottomcomposed o opposite inclined side portions extending upwardl into thetrap and spaced apart to provi e an entrance to the same and to form alower bait receivin space and adapted to direct flies upwar y into thetrap, the end walls of the trap being provided at the bait receivingspace with openings and havin marginal flanges located at opposite si esof the openings and projecting from the inner faces of the inclined sideportions of the bottom to direct flies or other insects inward.

t. A device of the class described including a trap or receptaclehavinga bottom composed of side portions spaced apart to provide an entranceto the trap or receptacle' and to form a lower bait-receiving space, atrough having inclined sides and open at one end, and a bait stripsupported by the trough and engaged by the sides thereof and adapted tobe introduced into the same and removed therefrom through the open endof the said trough.

In testimony, that I claim the foregoing as m own, I have hereto affixedmy signature in the presence of two witnesses.
